Installation / Commissioning
The C-Control PRO AVR32Bit UNIT is attached so that the mini-USB socket corresponds to the
marking (USB CON) on the Mainboard.
In the baseline condition, the jumper (JP1, JP2 and JP3) are not plugged.
The power supply of the Applicationboard occurs via a stabilized power supply or a laboratory
power supply with an output voltage of 7.5V and a minimum current of 500mA.
Install the C-Control PRO Development Environment "IDE" (Integrated Development Environment).
See installation software.
Install the USB driver.
Power Supply
The Applicationboard is powered by a stabilized plug-in or laboratory power supply (7.5 V/500mA).
Depending on the additional circuitry of the application motherboards it may be necessary later to
use a mains adapter with a higher power. Two fixed voltage regulators on the application board gen-
erate the stabilized internal supply voltage of 3.3V and 5V. The two LED's +3.3V and +5V indicate
the functionality of the power supply. All circuit components on the application board are supplied
with these voltages (see diagram). On the board, some ports are available to allow you to tap out the
different voltages. Make sure that the two voltage regulators are not getting too hot when using cus-
tom circuitry with higher loads. For larger loads, it is recommended to feed them externally!
The mass between external circuitry (power supply) and the Applicationboard must be the same!
The cooling surface of the voltage regulator is warm to hot during operation, depending on the
connected consumer!
I2C, UART and UNIT-Bus
The pins on connector J8 are firmly connected to the pins P34 (I2C SDA) and P35 (I2C SCL). The
UART4 interface is available at connector J9. The I2C bus is also connected directly to the UNIT-
BUS. The UNIT-bus levels the 3.3V of the UNIT to 5V and 5V signals to 3.3V (bi-directional level
shifter). C-Control I peripheral like I2C modules and other 5V circuitry can be connected to this bus.
The UART3 interface can be placed on the UNIT-BUS via the jumpers JP1 and JP2.
